PUNCHING AND THE LIKE MACHINE.

Specification of Letters Patent. I Patented M31111, 1919.

Applicatioii filed July 20, 1917. Serial No. 181,877.

To all whom it may concern:

Be it known that 1, WILLIAM Woon, a

subject of the King of Great Britain, and

residing in Birkenhead, in the county of Chester, England, have invented certain new and useful Improvements in Punching and the like Machines, of which the following is a specification.

This invention relates to machines for perforating metal plates and is particularly applicable to machines for punching the rivet holes in ships plates, and hasfor its object the improvement of such machines so as to render them suitable for automatically perforating holes in plates, the longitudinal disposition .of the centers of Which, instead of being in right lines are in lines of curved contour to suit the shear of the ship, so that V is an elevation of the central portion of the machine, the respective extensions to the right of the lineR, R, and to the left of the line L, L, being shown in Figs. 1 and 1 Fig. 2 is a plan view of the machine to a reduced scale.

, Fig. v3 is a fragmentary view, to an enlarged scale, of part of Fig. 2 and shows the hauling carriage; Figit being a similar view to Fig. 8, but showing the trailing carriage.

Fig. 5 is an elevation in transverse section on the line. V,.V, of Fig. 3.

Figs. 6 and 7 are respectively, an elevation, and an elevation in sectlon on the line.

V11, VII, of Fig; 3; Fig. 8 is a transverse sectionon the line VIII, VIII, of Fig. 6; and Fig. 6 is a fragmentaryend view of a part of Fig. 6. i

Fig.9 is an elevation viewed in the opposite direction to Fig. 1'; and Fig. 10 is a corresponding plan; Figs. 11, 12 and 13 are fragmentary views partly in section, of details shown in Figs. 9 and 10, and Fig. 14 is a fragmentary view of a modification.

Throughout the drawings the same parts are indicated'by the same letters or figures of reference, and in the case of sections the directions in which they are viewed are indicated by the small arrows placed adjacently to the lines denoting the plane of section.

A is the cross frame of the machine and it carries a series of punches P carried in a suitably guided cross girder p reciprocated by eccentrics p and eccentric sheaf frame 37 the eccentrics are mounted on a cross shaft a which is driven by the spur wheel a gearing with the pinion a on the shaft o (see Fig. 9) which is in turn driven by the spur wheel a (see. Fig. 1) gearing with the pinion a secured to the fly-wheel a and belt pulley a which is driven by any suitable means, say, an electric motor a".

The several punches are each fitted with an interposing plate 79 which when pushed in renders the punch operative, but which when withdrawn, as in Fig. 13, leaves the punch free to rise and fall without punching.

B is the guide bed of the machine carried from the frame'Aand feet I), and G is the traversing screw driven by speed change wheels c (Fig. 10), from the lay shaft 0 geared by the bevels 0 to the shaft 0* to 0* is prevented from rotating in the reverse direction, when the pinion rotation is reversed, by the brake band a coiled around the brake block 0 and fitted with a weight K is, the presser plate.

'The arrangements described are common to punching machines of this type and are illustrated to show the cooperation of perforating means and the traversing means with features of the invention described below, and need not further be described. They are given by way of example and it is to be understood that any suitable organization for perforating the plateseither by drilling or punching, and any suitable organization for imparting intermittent angular movement to the feed screw may be employed.

D is the hauling carriage, and E is the trailing carriage, and the plate F, to be per forated is attached, at the leading end, to a made to conform to the desired curvature requisite to impart to the said two parts, as they are moved longitudinally, the necessary transverse movement. g

In the arrangement illustrated, the leading end of the plate F is attached by the pinching screw (Z to the jaw-bracket (Z (Fig. 6) which in turn is threaded on to the sliding bar G and secured in position thereon by the pinching screw (Z The bar G is slidably mounted in aw extensions d of the pivoted par-t D of the hauling oarriage.

The pivoted part D is connected to the adjustable part D of the hauling carriage D by the pivot pin 6Z6 and is provided with runners (Z which'support the weight and run on the machined surfaces of the bed B, and is maintained in correct transverse alinment by depending portions cZ fitting between the inner edges 0]": the rails of the guide bed. The sliding bar G is guided in the jaw extensionsrl by anti-friction rollers (Z against which the bar presses when the plate is being hauled along; the jaw bracket d is provided with a runner (Z which bears on the horizontal web (Z of the part D (see Figs. 6 and 7). The hauling carriage D is fitted with runners (Z -which run on guide rails, being maintained in transverse alinement by the depending portion 13 (see Figs. 7 and 8).

Thehauling carriage D (see Figs. 6, 7 and 8.) is fitted with any suitable form of nut (Z adapted to engage with or to be disengaged from the traversing screw C; in the arrangement illustrated, which for the sake of simplicity is more or less dia grammatic, the nut Z is carried on the end of a screw d so that the lattercan rotate relatively thereto, the nut (Z being prevented from rotating on the screw; by a pin al when the screw (Z is rotated by a handle d": axial movement is imparted to the nut, causlng it to either engage or disengage as'may be desired. vThe adjustable part, D of the hauling carriage is adapted adjustablepart D and the pivoted part.

D connected thereto is obtained by means of the screw (Z which is journaled in the riage D and which screws into the bracket bracket d. carried from'the hauling carj (Z carried from the adjustable part D; V p

the fine adjustment of the plate axially in relation to the punches is thus obtained,

after which the two parts D and D of the hauling carriage may be secured together by the bolts (Z V It may be necessary, in the case of an exceptionally long plate, to attach it to j the haulingcarriage at an intermediate point, and for this purpose an angle bracketal is bolted .tothe vertical extension rZ Iof the jaw bracket 6Z I The trailing carriage E is adapted'to slide along the'guide bed B, and the rear of the 7 plate is attached to the jaw bracket by the pinching screw 6 the jaw bracket being threaded on the bar G and being fixed in position thereon by the pinching screw 6*. The bar G is carried in: the jaw ex-' tension c of the pivoted partE connected to the trailing carriage E by the pivot pin 6, the sliding bar being guided in by the antifriction rollers 6 It will be seen that the construction of the trailing carriage resembles that of the hauling carriage, with the exception that it is not necessary to provide it with an adj ustable portion-suchas D nor with a nut for connecting it to the traversing screw;

it may, however, be provided with runners similar to (Z shown on D, and the jaw bracket c na.y have a runner such as (Z running on a web on E ,such as (Z shown in connection with the hauling carriage.

Motion is imparted to the transversely moving port-ions of the hauling and trailing carriages respectlvely by guide tracks H and H. According to one modification (see Figs. 1, '3, 4 and 5) the tracks may consist of two rails h securedtogetlier by distance pieces 7L and fitted with a series of adjusting screws 7L located at suitable intervals; the screws 7L are carried at their outer ends by the framework 71, fitted with spherical seatings it against whichthe end locking nuts/z, bear; the inner ends of the the-jaws screws are carried in slotted brackets h I and are fitted with spherical collars k which locate them axially; the adjusting screws pass through the nuts 72 carried nonrotatably between the rails, and it will be seen that if the screws [L be rotated by the handle It, the rails, which are reasonably flexible, may be curved to such'contours as correspond with the shear lines of ships, plates.

the guide railsin accordance with the position of the latter which of. coursevaries the shear and length of.

in accordance with the plates.

Assuming that the machine is required to punch a ships plate having a given shear,

thenthe guide rails would beset by meansof the screws 71, to the requiredcontour in any convenientimanner; usually one side of the guide bed B would be taken as the base.

line, and the guide rails would be manipulated by the screws 7& so that thedistance from the said base atordinates spaced, say, to agree with the frame spacing ofthe ship would correspond withthe shear heights taken from the scrive board for the particular, plate, the corresponding ordinates on opposite sides of the line of punching being properly located in respect to the said line inaccordance with the length-of the plate to be punched; the contour of the two guides H and H would normally be similar curves,

and it will be seen, as theplate is connected 7 L 1 atthe one end to the sliding bar Gand at the other end to the sliding bar G, that as the hauling-carriage and the trailing carriage are drawn along longitudinally as the punching proceeds, each end of the plateis moved transversely, across the machine by the same amount and in accordance with the shear line. The contour of theguides H and H need not, however, be similar, and by selecting suitable contoursfor the respective guides, plates to be located, for example,

near the ends of a ship where the lines of holes of successive frames are not parallel, may be automatically punched.

In the modification illustrated in Fig. 14, a single guide rail H is employed instead of the double rails previously described; the construction of the adjusting screws may be the same as before, but the nuts h through which they pass are secured to the single and instead of single roller such asg on the ends of the bars G and G, the said bars are'each fitted with-a collar the stem of which passes through the bar and to the 11nd erside of which are fitted double rollers which respectively embrace opposite sides of the rail H. r p

The guides H and H may be duplicated, one of each being placed on each side of the machine, corresponding guiding means being provided on each end of the sliding bar G. When the machine is required to be used in the ordinary way without the guiding surfaces, the sliding bars may be turned through 180 so as tofree the engaging meansfrom the guidingsurfaces. ,7 r

In order to adapt the machine to deal with plates longer than the length of the guide bed provided with a guide screw, the haul: ing carriage may, in the first instance, be attached to the leading edge of the plate and therear of the plate is carried over the trailing vcarriage, the latter being attached to the plate some distance in front of the rearedge- When the plate carried in this way has been perforated as far as practicable, vthe trailing carriage is detached, moved rearwardlyand attached to the rear of the plate, the hauling carriage also being detached, passed rear wardlyunder the plate and secured to it at a point a corresponding distance in rear ofthe front edge. In ordervto guide the hauls ing and trailing carriages over the restof the forward movement of the plat e,-auxiliar Y uides H andH as shown in. Fi 2 I are provided, the opposite ends of thejslidmg bars G being arranged to engage with them and their curvature being so arranged that the plate is given the, same transverse movement as would have beenobtained had it been possible to continue the guide'surfaces H, H.
